On a recent vacation to Marco Island, a friend and I decided to do the "Backwater Adventure". On this excursion, you drive your own two person Craig Cat compact boat ( a small, two seater boat on what look like big water ski's). Once you get out past the no wake zone, you open the throttle and have the ride of a lifetime! The awesome guide, Jason takes the group on through the 10,000 islands mangroves and open waters where we saw UP CLOSE, more dolphins then we could count! Because the boats sit so low in the water, you can literally reach out and touch them if they get close enough to you. Most of them came within just a few feet of us, and one even dove right under me! We didn't see any manatees or turtles that day, although they often do. We stopped at one island to go shelling before heading back to the dock. The trip is not expensive and is so worth every penny! It was a crazy wonderful experience that I highly recommend!
